See why we call the retard "Silly Goose"? I knew he couldn't solve it. Another variation is sqrt((-x)^2), where the square is in the third quadrant, not the first. Same absolute area, but different squares. Androcles. Androcles

You are not asking a vector calculus problem. You are asking a problem that has no solution with valid mathematics because the starting assumption is invalid. Area is not a vector - area is a SCALAR. Area of a rectangle is defined as the magnitude of the two vectors that form the sides of the rectangle. Which, unsurprisingly, IS NOT A VECTOR. If you want me to answer a problem, reformulate it into mathematics that is actually taught in school and used by professionals rather than your shitty attempt at reinventing the wheel.

Go ask your teacher, I will not give you free e-tutoring any more.

Therefore, area can be construed as a vector, and in fact in many 3-D systems one has to be very careful lest the orientation of a face be incorrect and the face vanish. The volume of a parallelpiped is the triple-product. Therefore, for the question above: the length vector for the missing side is the cross-product of A and L, divided by the square of the norm of L. -- #191, ewill3(a)earthlink.net "640K ought to be enough for anybody." - allegedly said by Bill Gates, 1981, but somebody had to make this up! -- Posted via a free Usenet account from http://www.teranews.com

You are under the mistaken impression that you have anything worth teaching. |
